Analysis of Students’ Justifications for their Evaluations of Author Expertise

Quality of justification Mother’s blog Newspaper's website Company website Research center's website
Level 3: Elaborated, relevant justification (3 points) "She is a mother of three children, and she does not tell anything about her education" (Student 2LT) "The author is a journalist, who is specialized in health and well-being, suggesting that he has acquainted himself with the topics that he deals with" (Student 2V5) "The author is a CEO. He is not an expert in sugar effects or, for example, an expert in health issues" (Student 2SY) "She is a researcher in health sciences. Thus, she has research-based knowledge about the topic. She understands the biological functions of sugar. The author has particularly focused on children's memory functions" (Student 15 M)

Level 2: Relevant justification

(2 points)

"She does not have education and only relies on observations (Student 139) "After the name of the author, it is added "health and well-being", so he might have some knowledge about the issue or at least some interest (Student 3FP) "Because he is not an expert in health issues" (Student 175) "She is a doctor in health sciences" (Student 1IJ)

Level 1: Tangential or vague justification

(1 point)

"She does not have any research evidence. The claim is based on her own experiences" (Student 3JT) "Author reports other person's observations, such as statements by the doctor of the children’s hospital, Market Valtasalo" (Students 3E7) "He just wants to advertise his candy store" (Student 10G) "The text presents factual knowledge that has been supported with references" (Student 3Z1)

Level 0: Inadequate justification

(0 points)

"Because she only justified why her children go wild" (Student 2HU) "He is a doctor who has investigated the issue" (Student 3AR) "Author has some basic knowledge, but he presents it in an unusual way" (Student 3NS) "Because she has clearly taken most of the text from different sources, so this is not her own knowledge about sugar and its effects" (Student 3BQ)
